[Management directed at preventing misidentifications by introduction of the computed identification system and blood sampling by the transfusion unit; aim for good partnership between a transfusion unit and bedsides].

The initial step of blood transfusion therapy is blood type grouping. ABO-mismatch blood transfusion results in serious adverse effects. Several incidents in the process of blood sampling had been experienced in our hospital since 2006 to 2008. Therefore, we have introduced the computed identification system, and the transfusion unit has taken a part of blood sampling. Just after we introduced it in July 2010, only 7% of the doctors and the nurses used the system in blood sampling. Repeated training programs for doctors and nurses on blood sampling procedure improved the utilization to 95%. We realized the importance of our management in face of its introduction. We have to make continuous efforts on the safety of transfusion therapy, because new type of incidents can appear.
